Robert Pattinson may be the big star in the "Twilight" flicks -- but he's got nothin' on the co-star spotted on the set of his new film, "Water for Elephants."
R-Patz may have looked tiny in comparison to the giant pacaderm on the Ventura County, CA set yesterday ... but he sure looked pretty good in that white tank top!
(Check out more pics from the set!)
In the flick, Pattinson plays a young man who works for a travelling circus.
